SPRAY-BURNER.

Specification of Letters Patent.

Patented Dec. 2, T915.

\ ficient and economical 111 its operation, lnexpensive as tomanufacture, and one in which the atomizing disk is capable of rotationand is formed with a chamber or whirling cavity in its outer surface,thus dispensing with the spacing ring now commonly in use.

With the above mentioned and other ob je'cts in view, the inventionconsists in the novel construction and combination of parts hereinafterdescribed, illustrated in the accompanying drawings and pointed out inthe claim hereto appended; it being under-' stood that various changesin the form, proportion, size and minor details of construction withinthe scope of the appended claim may be resorted to without departingfrom the spirit or sacrificing any of the advantages of the invention. Pc

To more fully comprehend the invention, reference is directed to theaccompanying sheet of drawings wherein is disclosed the preferred formof my invention and in which-- Figure 1 is a longitudinal sectional viewof my improved device,disclosing the burner tip provided with a recessedouter end, the atomizing disk in the recess, the ported diaphragm andthe end cap. Fig. 2 is an end view of the device disclosing the end cap,the ported diaphragm, and in dotted lines the slots in the atomizingdisk. Fig. 3 ,is aperspective view of the atomizing disk, removed fromthe tip, disclosing the inclined slots therein and the annularflangeproviding a thereof. Fig. 4 is a side elevation of the atomizing disk,discloslng more fully the inclination of one of the slots.

ngs, wherein like characters of reference jjmsignate corresponding partsthroughout whirling chamber centrally of one face.

Referring more particularly to the drawthe several views, the numeral 1indicates a nozzle plpe, to the end of which is threaded aknozzle tip 2formed with the fuel conduit 3. The outer end of the nozzle tip 2surrounding the conduit 3 is formed with a circular recess 4 in which isadapted to be seated the atomizing disk 5, which is preferably of adiameter'slightly smaller than the diameter of the recess and preferablyof a thickness slightly less than the depth of the said recess. f

The atomizing disk is formed on one face, that which is positionedtoward the outer end of said nozzle tip, with an outwardly projectingannular fiange 6, which provides a centrally arranged whirling chamber 7in the outer face of the disk. Suitable apertures 8 are formed obliquelythrough the disk, and in the illustration the same are disclosed in theform of slots extending from the peripheral edge toward the center ofsaid disk, but it is to be understood that said apertures may be of anysuitable shape, just so long as the same extend through the .disk in adirection oblique to the faces thereof. v

. suitable diaphragm 9 formedwlth a central discharge orifice 9 ispositioned over the outer end of the nozzle tip and is retained inposition over the recess 4 'by'the flange 10 .of the end capll which. isthreaded on the'outer end of the nozzle tip 2.

The fluid forced under pressure through the nozzle pipe will strike theatomizing disk 5 and will be forced through the apertures 8 therein, theaction of the fluid passing through the oblique apertures causing thedisk to rotate in its seat and the fluid issuing from the apertures intothe whirling chamher? will be broken up and in the form of a spray, andthe rotation of the disk will, maintain the fluid in such conditlon, asthe same will issue therefrom with a whirling motion. By providing anatom z ng disk constructed as described; the opemngs m the same areprevented from clogging, owing to the rotation thereof. The atomlzedfluid collected in the whirling chamber will issue from the dischargeorifice 9' in the form of a fine spray, which will produce uniform andcomplete combustion in the furnace fire box.

It will be apparent that by :forming the whirling chamber in theatomizing disk that Ill have dispensed with the separate ring usu- Ially placed in the nozzle tip forthis purpose, and have provided anozzle composed of but few parts, one capable of being constructed atlittle cost and one thoroughly efficient for the use intended.

Having thus described my invention what is desired to protect by LettersPatent is.-

disposed whirling chamber in the outer face thereof, said disks'tbeingof a diameter less than the interior diameter of said recess and of athickness less than the depth of said recess and provided with aplurality of slots passing through the same in a direction obhque to thefacesthereof and each extending from the peripheral edge toward thecenter of the disk, a diaphragm positioned over and resting on the outerperipheral end of said burner tip and formed with a discharge opening inits center, and a flanged end cap fitted over the end of said burner tipfor retaimng said diaphragm in contact with said tip.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
